Abstract
The invention discloses a positioning method for elbow parts and provides a machining and positioning method for the elbow parts. According to the machining and positioning method for the elbow parts, the positioning method for the elbow parts is simple and high in positioning accuracy and efficiency, and the technical problems that the positioning accuracy is low, defective products are prone to be produced, and consequently the rejection rate of the parts is increased during machining of the elbow parts in the prior art are solved. The machining and positioning method for the elbow parts generally includes the steps that firstly, center data of flanges at the two ends of an elbow are detected out through a probe; then the data are compared and compensated; the compensated data are verified; and finally, procedural machining is performed through the compensated data.
Description
Technical field
The present invention relates to a kind of parts like bent pipes localization method, more particularly to a kind of simple, the accurate bend pipe of bend pipe positioning
Class part processing positioning method.
Background technology
Need to be accurately positioned when parts like bent pipes are processed, especially to foundry goods class bent pipe parts, traditional determines
Position method is clamping after line, due to the increase of crossed process, not only increases cost of labor, and low production efficiency.Existing casting
The processing of part parts like bent pipes is usually outer shape positioning, and because foundry goods overall dimensions deviation is larger, therefore clamping error is big, because
This part generates many defective products in actual production, and such as in uneven thickness, part occurs in processing rear flange is used to assemble
When, flange excircle misalignment, centre-to-centre spacing dimension overproof, processing rear flange hole deviation are big, or even directly result in part rejection.
The content of the invention
The present invention mainly provides the bend pipe class of a kind of simple parts like bent pipes localization method, positioning precision and efficiency high
Part processing positioning method, positioning precision is low when solving that parts like bent pipes are processed present in prior art, is also easy to produce
Defective products, causes the technical problem of part rejection rate increase etc..
What the above-mentioned technical problem of the present invention was mainly addressed by following technical proposals：Parts like bent pipes processing is fixed
Position method, including order below step：
1）Bend pipe clamping is taken on bend pipe positioning tool, and makes the flange face A and flange face B of bend pipe two-port outwardly；
2）On the basis of flange face A, flange face A center reference aa are detected and corrected with probe；
3）Theoretical flange face B center reference ba are conversed with the flange face A center references after correction；
4）With the theoretical flange face B center references ba for conversing as benchmark, with probe detection flange face B center references
Bb, calculates difference t=of detection flange face B center references bb and theoretical flange face B center reference ba（bb-ba）/ 2, and draw
New coordinate system；
5）Go out the center reference ab of flange face A with new coordinate system conversion again, calculate detection flange face A center reference aa
With difference y of ab；
6）The overproof alarming value n of default flange face A, overproof warning is carried out as y >=n, bend pipe and clamping is checked, if bend pipe
It is abnormal, report exception and remove, if clamping exception, after adjustment clamping, from step 1）Restart；
7）As y ＜ n, further according to step 5）In the center reference ab of flange face A that converses converse theoretical flange face B
Center reference ba ', calculates difference x of detection flange face B center reference bb and ba '；
8）Default flange face B ultrasonic difference alarming value m, overproof warning is carried out as x >=m, bend pipe and clamping is checked, if bend pipe is different
Often, report exception and remove, if clamping exception, after adjustment clamping, from step 1）Restart；
9）As x ＜ m, bend pipe positioning is qualified.
During positioning, first with A faces as roughing standard, probe detection A faces simultaneously correct, and with the A faces center after correction reason is conversed
By B faces center, B faces are gone to, then the B faces theoretical center conversed with A faces goes to detect B faces center as benchmark, now can find
There is error, then error is converted.Such as, probe data shows that B faces center is less than theoretical center value, just that B centers is past
The half of lower movement deviation value, now can produce a new coordinate system, then go out A faces center with new coordinate system conversion, and
A faces center is surveyed with this center, overproof warning is set, be then converted to B faces and go to detect B faces center, overproof warning, whole mistake are set
Cheng Ruguo can be passed through, you can carry out normal process, and otherwise clamping or part is had problems, detected by probe curved
Then data are compared and are compensated by the centre data of the end flanges of pipe two, then verify offset data, finally using offset data
Enter the processing of line program, relative to the conventional mapping methods of parts like bent pipes, localization method is simply effective, positioning precision and efficiency
Height, improves the product qualified rate of part processing.
Therefore, parts like bent pipes processing positioning method of the invention tool has the advantage that：Detected by probe first curved
Then data are compared and are compensated by the centre data of the end flanges of pipe two, then verify offset data, finally using offset data
Enter the processing of line program, relative to the conventional mapping methods of parts like bent pipes, localization method is simple, positioning precision and efficiency high,
Improve the product qualified rate of part processing.
Description of the drawings：
Fig. 1 is the clamping schematic diagram of parts like bent pipes of the present invention.
Specific embodiment：
Below by embodiment, and accompanying drawing is combined, technical scheme is described in further detail.
Embodiment：
As shown in figure 1, the parts like bent pipes processing positioning method of the present invention, including order below step：
1）The clamping of bend pipe 1 is taken on bend pipe positioning tool 2, and makes the flange face A3 and flange face B4 water of the two-port of bend pipe 1
Put down outwardly, and flange face A3 and flange face B4 is vertical with horizontal plane holding；
2）On the basis of flange face A3, flange face A3 center reference aa are detected and corrected with probe；
3）Theoretical flange face B4 center reference ba are conversed with the flange face A3 center references after correction；
4）With the theoretical flange face B4 center references ba for conversing as benchmark, with probe detection flange face B4 center references
Bb, calculates difference t=of detection flange face B4 center references bb and theoretical flange face B4 center reference ba（bb-ba）/ 2, and
Go out new coordinate system, for example, probe data show flange face B4 centers less than theoretical center value it is necessary to flange face B4 centers to
The half of lower movement deviation value；
5）Go out the center reference ab of flange face A3 with new coordinate system conversion again, calculate detection flange face A3 center references
